digestion system pt care Flashcards
average length of adult small intestine
22 feet
villi of small intestine
series of finger like projections, assist the process of digestion and absorption
1st portion of duodenum is called and why
duodenal bulb, because of appearance when filled with contrast
small intestine divided how
2 portions upper- jejunum lower ilieum
4 parts of colon (large intestine)
cecum colon rectum anal canal
haustra
series of pouches in large intestine
function of large intestine
reabsorption of fluids and elemination of waste
ileocecal valve
just below the juntction of the ascending colon and the cecum
anus
external part of colon, opening
peristalsis
contraction waves in which digestive tubes propels its contents toward rectum
average empty time of stomach
2-3 hours
time it takes barium to reach rectum
first 2-3 hours
last 4-5 hours
why fluro is used on alimentary canal
observe the canal in motion
contrast commonly used for alimentary canal
barium sulfate
pneumatic compression paddle commonly used
duodenal bulb-puts pressure on abdomen
room perparation
adjust equipment controls have foot board and shoulder support check spot films apparatus and make sure it is ready and enough IR abailable prepare required tyoe of contrast
alimentary canal begins and ends
mouth anus
cardiac antrum
terminal esophagus lies in abdomen
4 parts of stomach
cardia fundus body pyloric portion
cardia of stomach
section immediately surrounding esoageal opening
fundus and fills it when upright
superior portion of stomach expands superiorly and fills with gas
rugae
longitudinal folds
which curvature is longer
greater curve
cardiac orifice
where esophagus joins the stomach
pyloric orifice
opening between stomach and small intestine
pyloric sphincter
muscle controlling pyloric orifice
size, shae and position of stomach depends on
body habitus, posture, and amount of stomach contents
functions of stomach
digestion and food absorbtion
size of adult esophagus`
10 “ 3/4 diameter
3 parts of small intestine and its appearance
deodenum- c-shaped
jejunum- rough fluffy appearance
ileum-smooth
length of large intestine
5 feet
veriform appendix
attached to posterior and medial sides of cecum
most important consideration for GI radiography
elimination of matter
2 parts of digestive system
accessory glands alimentory canal
accessory gands of alimentary canal
salivary glands liver gall bladder pancreas
lesser curvature
right border of stomach begins at esophogastric junction and its concave curve ending at pylorus
greater curvature
left border begins at cardiac notch and follows superior curvature of fundus 4-5 times longer
where body of stomach begins
level of cardiac notch
describe the stomach
dilated saclike portion of the digestive tract extending between esophagus and small intestine
accessory pieces of fluor unit
film records, television system, spot film, cameras digital image cameras, videorecorders
esophagus originates at
c6
level where esophagus passes through diaphragm
t10
where esophagus meets stomach
esophagogastric junctrion t11
where body of stomach ends
verticle plane passing throught angular notch
4 subdivision of colon
ascending transverse descending sigmoid portion
cecum
pouchlike portion and is below the junction of the ileum and colom
transverse colon
longest most anterior and most moveable part of the colon which stretches horizontally across the abdomen
duodenum
8’ to 10 ‘ long widest port6ion of small intestine makes up 1st 1/5 of small intestine
pyloric portion
consists of pyloric antrum and narrow pyloric canal
